Hi, I have a huge test tomarrow on cellular respiration and I was wondering if anyone could give me any tips or any tricks in the facts that I should need to kno! I'll be back in half hour if anyone answers! PLease Answer!

Animations of ATP production in the mitochondria. Thomas Terry of the University of Connecticut has created excellent animations of electron transport and the ATP synthease enzyme. These animations help to explain how electron transport generates an electrical gradient that provides the energy necessary to produce ATP. Click on the various links for different animations.

Another animation of electron transport. I can’t get enough of these. I am including so many illustrations of this concept because it is very important. Plus, these are neat to watch. Hit the GO button in the lower left corner to start the show.

Introduction to glycolysis. Go to the questions at the bottom and click on each one. You can use the arrows at the top of each question page to proceed. Lots of information here if you can work your way through the site. I found that the Quicktime animations worked better on my computer.

Metabolic pathways of biochemistry. While in more detail than your text, this site presents you with excellent three-dimensional rotatable images of carbohydrate metabolism (glycolysis, Krebs cycle…), lipid metabolism, protein metabolism, and chemiosmosis (oxidative phosphorylation). I had some trouble connecting to the 3-D plug-ins.

I just had my cell respiration test and I bet I got a question wrong...if anyone has the answer...please respond.
A certain bacteria lives in the waters of Yellow Stone National Park. THe water is naturally filled with cyanide. Why haven't the organisms died?

Cyanide (CN) acts as an electron arrestor, affecting the electron transport system, removing the electrochemical gradient and halting oxidative phosphorylation of ATP. Since this bacteria is unaffected by CN, it prolly generates all its required energy by glycolysis which functions perfectly well, CN or no CN. Fun question, makes you think (takes notes for future use)

yeah thats definitely something good to think about. CN, along with some other compounds, do arrest electron transfer or capture electrons themselves therefore halting an electron transport system. most organisms that live in the presence of these compounds are either facultative anaerobes that can utilize the ETS when O_2 is present but also possibly obligate anaerobes that predominantly create ATP much more slowly by glycolysis and will die in the presence of molecular oxygen.

hey..
i am in high school too!(grade11)
and i just learned about the stuff u were talking about..
the process in which cell produce only about 2 ATPs and its an anaerobic process called fermentationthis process starts with glycolysis and since the body doesnot receive enough oxygen,so it produces lactic acid or alcohol.there are two types of fermentation [b]lactic acid fermentation[/b],it occurs in some bacteria and mammalian muscle cells . 2nd type is alcohol producing fermentaion, occurs in yeast and bacteria (used it production of wine)

I am affraid you are terribly wrong sophisticated_sensation. There are 4 types of fermentations: lactic, alchoolic, butiric and acetic. Acetic permentation is the most controversed one because it an aerob process.
Fermentation produces a little more than 2 molecules of ATP: 16-30 kcal
If anyonw would like me to present this subject in a higher detail, tell me. I don't like writing things with no reason

Glycolysis realeses 2 molecules of ATP. Everyone knows that nothing in nature happens without a reason, so there must be a reason why the cell transforms piruvic acid into lactic acid or alcohol or any other of the products formed by fermentation. The reason is obvious: more energy. You will not find this in any book so do not look. If anyonw has a different opinion say so. I believe it is logical
